To calculate the volume of earth that is removed, we first need to convert the area of the mine from hectares to square meters:

75 hectares * 10000 m^2/hectare = 750000 m^2

Now, we can calculate the volume of earth that is removed by multiplying the area of the mine by the depth it was dug to:

Volume = Area * Depth

Volume = 750000 m^2 * 200 m

Volume = 150,000,000 m^3

Therefore, the volume of earth that is removed from the mine is 150,000,000 cubic meters.

75 hectares * 10000 m^2/hectare = 750000 m^2

Now, we can calculate the volume of earth that is removed by multiplying the area of the mine by the depth it was dug to:

Volume = Area * Depth

Volume = 750000 m^2 * 200 m

Volume = 150,000,000 m^3

Therefore, the volume of earth that is removed from the mine is 150,000,000 cubic meters.
